Why Grade IC8250

Iscar’s IC8250 sits between general-purpose and high-performance offerings — strong enough for production medium turning on steel, conservative enough to forgive the occasional spike in feed rate. DIAMOND layer keeps cutting temperatures workable.

Features & Benefits

100% Genuine Iscar – Original product with full quality guarantee, traceable batch.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
DIAMOND Coating – Superior wear resistance and extended tool life under continuous load.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Medium Turning of steel in production CNC lines
Holds dimensional tolerance over multiple indexings (insert)
Designed for shop conditions typical of Iscar tooling users worldwide
Pairs well with through-coolant setups for chip evacuation

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects Iscar’s production-grade tolerances rather than economy substrate.

Note: Compatible tool holders sold separately. Please confirm insert-holder seat compatibility (e.g. ISO seat designation) before ordering.
